Epic cinematic 8k wallpaper of Ellen Ripley, her face both resolute and fearful from the Alien movie. She wears a distressed tank top, portrayed in a wide-angle, action-oriented half-body shot. Her forehead and cheeks glisten with sweat, captured in a close-up, perfectly centered composition. Pressing her back against the cold metallic wall of the Nostromo space shuttle, she stands in a dimly lit, futuristic room. Sci-fi elements intertwine with Ray Tracing effects, creating a dramatic rim light around her form. Ultra-detailed and pristine in quality, the scene exudes cinematic excellence, embodying a dark, moody atmosphere. Lumen reflections mix with ambient lighting for a sophisticated 4k finish. Inspired by vogue and mastered with Rembrandt lighting, the image showcases high contrast and shallow focus. RTX ray tracing lighting amplifies the ultra-realistic appearance, encapsulated with an octane render finish in stunning 8K.
